U.S. Sens. Debbie Stabenow and Carl Levin have sent a letter to Secretary of State John Kerry asking him to stop a Canadian proposal to build a nuclear waste facility near Lake Huron.

Stabenow and Levin said they have "serious concerns" about the proposed nuclear dumping ground in Kincardine, Ontario, which is about 120 miles upstream from Lake Huron intakes that provide drinking water for much of Southeast Michigan.

“The placement of this nuclear waste storage facility is of great concern given its location near Lake Huron and the importance of the Great Lakes to tens of millions of U.S. and Canadian citizens for drinking water, fisheries, tourism, recreation, and other industrial and economic uses,” Levin and Stabenow wrote in the letter, sent Monday.

“We believe that the decision to store such large quantities of nuclear waste along the shores of an internationally shared resource must be thoroughly reviewed and considered by both countries,” Levin and Stabenow wrote in the letter.
